Pressed Crucibles

DysonTC's Crucibles - for Air and Induction Melting Applications

Dyson’s Isostatically Pressed Crucibles are used in a wide range of melting applications from the melting of basic Carbon steels to the melting of exotic alloys such as Nickel and Cobalt based super alloys.

Dyson Technical Ceramics™ use high purity raw materials and our dedication to quality ensures our products provide optimum & consistent performance. In addition to this Dyson’s efficient manufacturing techniques make sure our clients receive what they need, when they are needed.

In order to provide quality products Dyson delivers materials of the highest quality to the market, competitively priced and backed by the expertise of application knowledge and the resources of the DTC Research and Development Laboratory in Sheffield, England.

Material Selection

Selection of materials is made by reference to an extensive application database, which in conjunction with close liaison with end users, provides materials offering optimum performance in terms of cost and operation. Dyson Technical Ceramics™ manufactures  a wide range of compositions to suit most melting requirements. These compositions include:


Resistant to high temperatures with excellent erosion resistance properties, used in the melting of precious metals and exotic alloys used in the medical and aerospace industries.  Dyson manufacture Ceria, Magnesia and Yttria stabilised Zirconia.


Widely used for melting basic carbon steel alloys, stainless steels and less aggressive precious metals.  Where thermal stress is an issue, Dyson also manufacture an Alumina Mullite composition.


An excellent alternative to Alumina. The addition of Zirconia provides increased erosion resistance properties to extend the life of the crucible.

Isostatically Pressed Crucibles Products

  • Alumina Crucibles, AZ76Magnesia Crucibles, Alumina Crucibles

    Alumina Crucibles

    Dyson Technical Ceramics™ Isostatically Pressed Alumina Crucibles offer resistance to high temperatures, while maintaining good erosion resistance. Dyson Technical Ceramics manufactures a range of crucibles based on Alumina.


  • Crucible Backing Material

    Dypack Backing Material

    Complimenting Dyson’s range of crucibles Dyson Technical Ceramics also offer thermal insulating Dypack™ backing material, which can be used in air and induction melting applications.  Also referred to as “Ramming Material” or “Crucible Back-up”, it creates a safety barrier in the unlikely event of a crucible failure.  The crucible back-up also insulates the crucible, helping reduce changes in temperature that can cause thermal stress.

  • Zirconia Ceramic FiltersDyson Zirconia Ceramic Filters

    Zirconia Ceramic Filters

    Dyson Technical Ceramics™ Zirconia Ceramics Filters are used in the filtration of Steel and Nickel/Cobalt based superalloy castings. DysonTC’s Zirconia Ceramic Filters offer resistance to high temperatures, while maintaining excellent erosion resistance. The fine textures of the filters provide excellent filtration properties, giving the caster cleaner melts and reducing the need for grinding/machining. Advanced production techniques help to give the filters an even 3D lattice, resulting in a smooth, non-turbulent melt flow.

  • Zirconia CruciblesCrucible Backing Material

    Zirconia Crucibles

    Dyson Technical Ceramics™ manufactures a wide range of high performance pressed Zirconia Crucibles, based upon partially stabilised Zirconia. Zirconia Crucibles are often used in the precious metals, aerospace and biomedical industries.  Applications include the investment casting of Nickel, Cobalt and Chrome containing alloys, along with high temperature melting and refining of Platinum Group Metals (PGMs').
